Identify the rational function whose graph is given below. Note the function has an x-intercept at x=1 and a y-intercept at y=12. Three curves on a coordinate plane. A coordinate plane has a horizontal x-axis labeled from negative 6 to 5 in increments of 1 and a vertical y-axis labeled from negative 5 to 5 in increments of 1. A graph has three branches. From left to right, The first branch is below the x-axis and to the left of x equals negative 1, approaching both. The second branch falls from left to right between the two branches, passing through left-parenthesis 0 comma 0.5 right-parenthesis and left-parenthesis 1 comma 0 right-parenthesis, approaching x equals negative 1 and x equals 2. The third branch is above the x-axis and to the right of x equals 2, approaching both. Provide your answer below: $$f(x)=
